POST and boot specifications
When the switch is powered on or rebooted, it performs POST. Total boot time with POST can be
several minutes. POST can be omitted after subsequent reboots by using the fastboot command
or entering the diagDisablePost command to persistently disable POST. For more information
about these commands, see the Fabric OS 7.0.x Command Reference Manual.
POST
You can monitor the results of the diagnostic tests that run during POST through LED activity, the
error log, or the CLI. POST includes the following tasks:
• Conducting preliminary POST diagnostics
• Initializing the operating system
• Initializing hardware
• Running diagnostic tests on several functions, including circuitry, port functionality, memory,
statistics counters, and serialization
To determine whether POST completed successfully:
1. Inspect the switch LEDs to determine whether components are operating properly.
See Table 9 (page 49) and Table 10 (page 51) for descriptions of LED patterns. If one or
more LEDs do not display a healthy state, verify that the LEDs are not set to beacon by entering
the switchshow command to detect if beaconing is active.
2. Verify that the switch prompt is displayed on a workstation connected to the switch.
If there is no switch prompt when POST is complete, press Enter. If the switch prompt still does
not appear, open a Telnet session or access the switch through another management tool. If
this does not solve the problem, the switch did not complete POST successfully. Contact your
switch supplier for repair.
3. Review the switch system log for errors.
Any errors detected during POST are written to the system log, accessible through the errShow
command.
For information about error messages, see the Fabric OS Message Reference Manual.
Boot
Boot occurs after POST is complete and includes the following tasks:
• Performing universal port configuration.
• Initializing links.
